In the log of the squid proxy cache server me and some warnings are coming out every time I leave the proxy fails to resolve normally, it starts to take to resolve.
WARNING: no_suid: setuid(0): (1) Operation not permitted
I solve the above problem by restarting the squid proxy server, but after a while the same thing happens to me.
I was looking at the logs and I see other warnings but nothing abnormal.
UPDATED:
My OS is Ubuntu 12.04 Server 64bit and Squid 3.4.4.

--with-squid=/build/buildd/squid3-3.4.4
And add user proxy:
sudo adduser --system proxy
The squid server proxy normally rises and can navigate, I spent a few minutes or hours, starts to get slow and I always get the above error.
My idea of putting problem is the problem of cache with user privileges on the proxy.
Thanks in advances.
